Semiquantitative Method

Electrical resistivity measurements provide a semiquantitative method for estimating the water content of a rock. Techniques for measuring resistivity along tunnel walls and in horizontal drill holes were used in the Area 12 tunnel complex at the Nevada Test Site prior to the Atomic Energy Commission’s Hardtack Phase II test series during the fall of 1958. The results indicate that in future underground tests where the amount of water in the rock must be determined, resistivity measurements can be used to estimate water content, with only a limited number of samples needed to check the results.

AbstractElectrical resistivity measurements were made in a series of closely spaced holes drilled to the base of Storglaciären. Electrodes were lowered to the bottoms of the holes where they made contact with the substrate beneath the glacier. The measurements show that a layer of till, ~0.4–0.7 m thick, is present at the base of the glacier. The low resistivity of the layer indicates that it has a high water content, compared with tills of similar composition in the pro-glacial environment. A marked reduction in resistivity after a heavy rain storm demonstrates that the water content is sensitive to variations in water input at the surface.
